Since when did it become the government's business to "go into this" while playing with tax payer money? How do you save oil and pollution when you have to generate electricity somewhere else to charge all those batteries? All you are doing is shifting where the energy is produced. And why are we "saving" the cheapest and most plentiful source of energy we have, while wasting BILLIONS on systems not ready for prime time? Did Obama sign an Executive Order suspending the laws of supply and demand while I wasn't looking?
